Human Heart Anatomy Quiz

Aorta

• Major artery that carries oxygenated blood from the heart to the rest of the body.

Left pulmonary artery

• Transports deoxygenated blood from the right ventricle to the left lung for oxygenation.

Left pulmonary veins

• Four veins that carry oxygenated blood from the left lung back to the left atrium.

Auricle of left atrium

• A small, ear-shaped pouch that expands the volume of the left atrium and aids in increased blood capacity.

Left atrium

• Chamber of the heart that receives oxygen-rich blood from the lungs via the pulmonary veins.

Apex

• The pointed tip of the heart, located at the bottom, where the heart's contraction is strongest.

Great cardiac vein

• Vein that drains blood from the heart muscle (myocardium) and returns it to the coronary sinus.

Left ventricle

• Chamber of the heart responsible for pumping oxygenated blood to the body; walls are thick due to high pressure requirements.

Right ventricle

• Chamber that pumps deoxygenated blood to the lungs for oxygenation.

Middle cardiac vein

• Vein that drains blood from the posterior part of the heart and empties into the coronary sinus.

Posterior interventricular artery

• Artery that supplies blood to the posterior walls of both ventricles and the interventricular septum.

Posterior vein of left ventricle

• Vein that drains blood from the left ventricle and leads to the coronary sinus.

Right coronary artery

• Artery supplying blood to the right side of the heart, including the right atrium and ventricle.

Coronary sinus

• Large vein that collects deoxygenated blood from the heart muscle and drains it into the right atrium.

Inferior vena cava

• Major vein that carries deoxygenated blood from the lower half of the body to the right atrium.

Right atrium

• Chamber of the heart receiving deoxygenated blood from the body through the superior and inferior vena cavae.

Right pulmonary veins

• Carry oxygenated blood from the right lung to the right atrium.

Right pulmonary artery

• Transports deoxygenated blood from the right ventricle to the right lung for oxygenation.

Superior vena cava

• Major vein that brings deoxygenated blood from the upper half of the body to the right atrium.
